OK, let's try one device at a time. I'll start with the w5100. Compile and upload this code. What ip does the serial monitor show? It should be 192.168.2.2.
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,2,2);
void setup() {
Serial.begin(9600);
// disable SD SPI
pinMode(4,OUTPUT);
digitalWrite(4,HIGH);
// Start ethernet
Serial.println(F("Starting ethernet..."));
Ethernet.begin(mac, ip);
digitalWrite(10,HIGH);
Serial.println(Ethernet.localIP());
delay(2000);
Serial.println(F("Ready"));
}
void loop() {
}
edit: I mean initialize one at a time. Leave the SD card in the slot for this test.
